In cases of headache associated with head trauma or a significant intracranial hemorrhage, a consumptive coagulopathy, such as thrombocytopenia, and prolonged prothrombin and activated partial thromboplastin times may be evident. Thus, a complete blood count (CBC), prothrombin time (PT), and activated partial thromboplastin time (aPTT) may be indicated in such cases.

Check anticonvulsant levels in patients with a headache and a known history of epilepsy because adequate seizure control usually prevents the headache.
